My baby won't sleep

My baby is 1 week old and will not sleep at night, she spends most of the day asleep and won't stay awake longer than 10/15 minutes but at night she can be awake for 3 hours straight. Last night she was awake from 11pm-3am, she was fed, burped & then I changed her which woke her up and she waned feeding again, so I fed her and she projective vommited all over me & my bed, so I had to change her & that again woke her up & she wanted feeding again.. It's a never ending cycle. I don't know what I'm doing wrong or what to do but I just need help. I'm waiting to call the midwife/health visitor but can someone please give me any advice
